Villagers no longer get angry when you kill the iron golem

Not a bug, there is just no gossip category for iron golems being attacked, so villagers will not adjust prices according to that.

they did before 1.14

Can't say i've ever known villagers to get angry from killing golems, maybe i just didn't notice

Though it is basically impossible to know without looking at the wiki, villages before 1.14 had a "reputation score" system that changed when you traded with villagers, hurt villagers, and killed iron golems. When you killed an iron golem, you lost 5 "reputation points". If your reputation was low enough, iron golems were hostile instead of neutral. This old reputation system was basically useless and irrelevant because there were no iron golems in villages, however an important feature of it failed to pass on into the new reputation system.

Can confirm in 1.17.1.

Can confirm this in 1.18 Pre-release 6. Here are some extra details regarding this problem.
